91° on Nov. 13, 1986, the hottest reading for this week of the year since 1941. Next is 90° in 1946.
Lake Hamilton’s center stands about 140 ft above sea level. Within three miles the land runs from 100 ft to 210 ft, a difference of 110 ft: gently rolling country. The highest named summit within 15 miles is Iron Mountain, about 330 ft, 8 miles south-southeast.
Under the town center the state geologic map shows Cypresshead Formation (sand), from the Late Pliocene, 2.6 to 3.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 9 mi of the line.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 8 mi of the line.
Sand. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 4 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Lake Hamilton reaches the Gulf of America by way of Peace Creek and the Peace: about 130 river miles.
110 miles of the trip are on the Peace.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lake Hamilton; river miles along the main stem, rounded.
Lake Hamilton has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 52° in January. About 46 inches of rain fall in a normal year.
On November 14 Lake Hamilton normally reaches 80° and falls to 60°. The record high is 90°, in 1956; the record low 35°, in 1968. The most rain on this date, 2.00 in, fell in 1969.
Normals 1991–2020 and records since 1941 from the Winter Haven Area threaded record (Winter Haven Gilbert Airport, 8 miles west). NOAA, through RCC-ACIS.
